Delta Partners with JetZero to Develop Revolutionary Blended-Wing Aircraft

In a bold step toward sustainable aviation, Delta Air Lines has announced a partnership with JetZero to develop a blended-wing-body (BWB) aircraft. This innovative design promises to be 50% more fuel-efficient than traditional tube-and-wing aircraft, marking a significant milestone in the aviation industry’s journey toward reducing carbon emissions. The collaboration was revealed on March 5, 2025, and is part of Delta’s broader commitment to achieving net-zero emissions by 2050.

What Is a Blended-Wing-Body Aircraft?

The BWB design merges the wings and fuselage into a single, seamless structure, creating a more aerodynamic and fuel-efficient aircraft. This design reduces drag, increases lift, and allows for a lighter overall structure. The aircraft will also be capable of using sustainable aviation fuel (SAF), further reducing its environmental impact.

JetZero, a California-based startup, has been at the forefront of BWB development. The company received a grant from the U.S. Air Force in 2023 to build a full-scale demonstrator, which is expected to take its first flight in 2027. Delta’s partnership will provide operational expertise and support to accelerate the commercialization of this groundbreaking technology.

Key Features and Benefits

The BWB aircraft offers several advantages over traditional designs:

• Fuel Efficiency: Up to 50% less fuel consumption compared to current mid-range aircraft.
• Passenger Capacity: Can carry more than 250 passengers, comparable to existing widebody jets.
• Noise Reduction: Engines mounted on top of the aircraft significantly reduce noise levels.
• Sustainability: Designed to operate with SAF, further decreasing lifecycle carbon emissions.
• Airport Compatibility: Fits within existing airport infrastructure, ensuring seamless integration into current operations.

Delta will also collaborate on the interior design of the aircraft, aiming to enhance the passenger experience with features like dedicated overhead bin space, accessible seating, and fewer rows for a more spacious cabin.

Delta’s Role in the Partnership

As part of its Sustainable Skies Lab, Delta will leverage its operational expertise to help JetZero bring the BWB aircraft to market. The airline will provide insights into maintenance, operations, and customer experience to ensure the aircraft meets the needs of both passengers and airlines. This partnership is Delta’s fourth major initiative under its Sustainability Roadmap, which was launched in 2023.

“Working with JetZero to realize an entirely new airframe and experience for customers and employees is bold and important work to advance the airline industry’s fuel-saving initiatives and innovation goals,” said Amelia DeLuca, Delta’s Chief Sustainability Officer (source).

A Step Toward Net-Zero Emissions

The aviation industry has long been under pressure to reduce its carbon footprint. While advancements in fleet efficiency have improved fuel consumption by 80% over the past 50 years, more radical solutions are needed to meet global climate goals. The BWB aircraft represents a significant leap forward, offering a viable path to decarbonizing air travel.

JetZero’s CEO, Tom O’Leary, emphasized the importance of this partnership: “The ability to realize such significant efficiency gains in the near future meaningfully impacts the industry’s commitment to reach net-zero emissions by 2050” (source).

Looking Ahead

The first commercial BWB aircraft is expected to enter service by 2030, with Delta playing a pivotal role in its development and deployment. This partnership not only underscores Delta’s commitment to sustainability but also positions the airline as a leader in the next generation of aviation technology.

As the aviation industry continues to innovate, the Delta-JetZero collaboration serves as a reminder that bold, forward-thinking partnerships are essential to building a more sustainable future for air travel.
